So did I.

According to Michaël Grünewald on 5/29/2008 4:21 PM:

Which section did you have in mind for this improvement?  There is no
3.3.1 in the 2.62 manual:

I feel sorry, I should have checked that my manual is up to date, the correct section numbering is 4.8.1, its URL is


it is just the section you are referring to below.

This is where the improvement could go.

There is - use abs_top_srcdir.

You may want to consider upgrading to 2.62.

Where in the manual did you find that?  The correct address should be
'address@hidden' and not bug-gnu-utils.  I don't see the
bug-gnu-utils anywhere in the 2.62 manual.

Well, my manual is quite outdated. Quite surprisingly I have 2.13's manual with 2.61 installed. (I run FreeBSD, with a quite up-to-date port tree.)
All the best,
